pam_get_item(const pam_handle_t *pamh, int item_type, const void **item);
DESCRIPTION
The pam_get_item function stores a pointer to the item specified by the item_type argument in the location pointed to by the item argument.
The item is retrieved from the PAM context specified by the pamh argument. If pam_get_item fails, the item argument is untouched.
The following item types are recognized:
PAM_SERVICE The name of the requesting service.
PAM_USER The name of the user the application is trying to authenticate.
PAM_TTY The name of the current terminal.
PAM_RHOST The name of the applicant's host.
PAM_CONV A struct pam_conv describing the current conversation function.
PAM_AUTHTOK The current authentication token.
PAM_OLDAUTHTOK The expired authentication token.
PAM_RUSER The name of the applicant.
PAM_USER_PROMPT The prompt to use when asking the applicant for a user name to authenticate as.
PAM_AUTHTOK_PROMPT The prompt to use when asking the applicant for an authentication token.
PAM_OLDAUTHTOK_PROMPT
The prompt to use when asking the applicant for an expired authentication token prior to changing it.
PAM_HOST The name of the host the application runs on.
PAM_SOCKADDR The sockaddr_storage of the applicants's host.
PAM_NUSER The ``nested'' user if this is a login on top of a previous one.
See pam_start(3) for a description of struct pam_conv.
